Mōdraniht (Old English "Night of the Mothers" or "Mothers'-night") was an event held at what is now Christmas Eve by the Anglo-Saxon Pagans where a sacrifice may have been made. The event is attested by the medieval English historian Bede in his 8th-century Latin work De temporum ratione. Scholars have proposed connections between the Anglo-Saxon Mōdraniht and events attested among other Germanic peoples (specifically those involving the dísir, collective female beings, and Yule) and the Germanic Matres and Matrones, female beings attested by way of altar and votive inscriptions, nearly always appearing in trios.
In De temporum ratione, Bede writes that the pagan Anglo-Saxons:
Incipiebant autem annum ab octavo Calendarum Januariarum die, ubi nunc natale Domini celebramus. Et ipsam noctem nunc nobis sacrosanctam, tunc gentili vocabulo Modranicht, id est, matrum noctem appellabant: ob causam et suspicamur ceremoniarum, quas in ea pervigiles agebant.
Modern English translation:
[...] began the year on the 8th kalends of January [25 December], when we celebrate the birth of the Lord. That very night, which we hold so sacred, they used to call by the heathen word Modranecht, that is, "mother's night", because (we suspect) of the ceremonies they enacted all that night.
Scholars have linked these Modra ("Mothers") with the Germanic Matres and Matrones.Rudolf Simek says that Mōdraniht "as a Germanic sacrificial festival should be associated with the Matron cult of the West Germanic peoples on the one hand, and to the dísablót and the Disting already known from medieval Scandinavia on the other hand and is chronologically to be seen as a connecting link between these Germanic forms of cult." Scholars have placed the event as a part of the Germanic winter period of Yule.
Regarding Bede's attestation, scholar Philip A. Shaw (2011) comments that "the fact that Bede's modranect can be to some extent confirmed by the Romano-Germanic votive inscriptions to matrons does at least indicate that we should not be too quick to dismiss the other evidence he provides for Anglo-Saxon deities".
